均一に加温される。First, when germinating flower seedlings such as chrysanthemums in the storage 1, they are stored in the storage room 10 and the changeover switch 34 is set to the heating mode as shown in FIG.
When the changeover switch 34 is set to the heating mode, the common terminal 41 closes to the terminal 40, the contact 42 closes, and the contact 46 opens. In this state, when the three-phase 200V power is supplied to the control device C, the power lamp 33W and the heating lamp 33I are energized and turned on. For example, assuming that the outside air temperature is low and is equal to or lower than + 10 ° C. in a night such as winter,
Since the outside air temperature thermostats 28 and 29 close the contacts, both the first and second heaters 23 and 24 are energized to generate heat. Here, the second blower 18 is always operated from the power-on, and circulates the air heated by the two heaters 23 and 24 in the air circulation space 11 uniformly as shown by arrows in FIG. 2 or FIG.

る。Further, when the outside air temperature rises and becomes higher than + 10 ° C., the first outside air temperature thermostat 28 opens the contact point, so that the heat generation of the first heater 23 is stopped and the inside of the air circulation space 11 is kept in the second space. The heating is performed only by the heater 24. Further, when the outside air temperature rises and becomes higher than + 20 ° C., the second outside air temperature thermostat 29 also opens the contact, so that the heat generation of the second heater 24 also stops. When the outside air temperature is low, the temperature in the storage room 10 is also low, so it is necessary to strongly heat the inside of the storage room 10. However, as the outside air temperature increases, the temperature of the storage room 10 tends to increase. Therefore, if both heaters 23 and 24 generate heat in a state where the outside air temperature is high, the inside of the storage room 10 will be excessively heated. However, in the present invention, when the outside air temperature becomes higher than + 10 ° C., the heat generation of the first heater 23 is stopped, and the heating is switched to the heating only by the second heater 24 to reduce the calorific value. can do.
In particular, two outside temperature thermostats 2 with different set values
Since the calorific value is changed by 8, 29, a simple mechanical thermostat can be adopted, and the cost is reduced.

とされる。With these controls, the interior of the storage room 10 is uniformly heated to a temperature of about + 25 ° C. irrespective of fluctuations in the outside air temperature, so that an environment suitable for germination and growth of seedlings such as chrysanthemums can be constituted. Become. This eliminates the need for a conventional germination and growth operation using a greenhouse or the like. If the temperature inside the storage room 10 becomes abnormally high at + 30 ° C. or more due to a further rise in the outside air temperature or the like, the electronic thermostat 31 closes the contact point 44, so that the cooling device 14 is energized (the thermostat 43 is naturally turned on). (Closed), the compressor 21 and the first blower 13 are operated, and heat exchange with the cooler 12 is performed, and the cooled cool air is blown into the air circulation space 11. Thereby, the inside of the storage room 10 is cooled from the wall surface of the inner box 3, and the temperature is lowered. Electronic thermostat 3
1 opens the contact point 44 at a temperature of, for example, + 20 ° C., and by these controls, the interior of the storage room 10 is set to an environment optimal for germination and growth of seedlings.

苗の老化も防止される。Assuming that the set temperature in the storage room 10 in the cooling mode is 0 ° C., the thermostat 43 opens the contact when the temperature in the air circulation space 11 becomes, for example, −3 ° C. When the temperature rises to ° C, a closing operation is performed. As a result, the compressor 21 of the cooling device 14 and the first blower 13 are controlled to operate and stop, and the cool air that has exchanged heat with the cooler 12 is supplied from the first blower 13 to the air circulation space 11.
It is discharged into. The air is uniformly circulated in the air circulation space 11 by the second air blower 18 which is constantly operated as described above, as shown by arrows in FIGS. Thereby, the wall surface of the inner box 3 is cooled to an average of about −2 ° C.
The inside of 0 is indirectly cooled from the wall surface of the inner box 3 and is maintained at about 0 ° C. Moreover, since the drying in the storage room 10 is suppressed by such indirect cooling and the humidity is maintained at a high level, the seedlings after the germination and growth can be stored with good freshness. Furthermore, since the ethylene gas generated from the seedlings is adsorbed on the green tuff R, the aging of the seedlings due to the ethylene gas is also prevented.
